Website to call a file and update at regualr intervals
We currently run a powerpoint presentation to show students the status of repairs and when their laptop is ready for collection from the ICT support team. We have a monitor mounted in a foyer for students to view. This is monitor is linked to a computer running a powerpoint presentation.
We are currently having to stop the powerpoint and edit when the status of a repair changed. This is about 10-15 changes a day, each time having to vnc to the computer running the presentation and editing the file.
How can I create a single file that can be updated and linked to the school website that reads this file and refreshes the page at a 30 minute or so interval?
I have very limited knowledge of website creation as our website is outsourced. And even more limited knowledge on creating a website that calls data from a file that is constantly updated!!
